The emergence of dinosaurs as dominant species on Earth can be traced back to a significant event in the geological history: the end-Triassic extinction. This event, which occurred approximately 201 million years ago, had profound implications for the evolution of life on our planet.

Prior to the extinction, various archosaurs, a group of reptiles that included dinosaurs, coexisted with other species. However, the end-Triassic extinction marked a turning point in their fortunes.

The mass extinction event eliminated nearly all of the archosaurs that had been competing with dinosaurs for resources and territory. This sudden depletion of competitors created a unique opportunity for dinosaurs to thrive.
